What is the firmware version?
Also, do you have an ASMedia ASM1062 controller to try (often seen on
motherboards for additional SATA ports)? That's the one I tested with.
Before tried with AMD chipset ones, but on those the 860s are known[1] to
have serious NCQ issues in general, not just TRIM, so they are not useful for
this test.
With ASMedia only queued TRIM fails and everything else works fine. So I
wonder if 850's queued TRIM issue in 860's case remains only on some SATA
controllers.
